μm was initially coated by chemical vapor reaction (CVR): a simple and cheap technique to prepare the SiC coating via siliconizing the substrate that was exposed to the mixed vapor (Si and SiO2... composites. A complex technology with two-step technique for preparing a dense SiC coating on C/C composites was developed. The inner coating was firstly prepared by chemical vapor reaction (CVR......
of refractory steel by plasma spraying technique. 2) The coating mainly consists of ZrO2 and Ni3Al. The microhardness of sprayed pattern surface is increased remarkably. 3) The dense oxidation film...

be studied and developed. Physical vapor deposition(PVD) is a clean environmental friendly technique, and does not produce wastes or appreciable atmospheric emissions[8]. Several PVD coating systems... technique has not been reported. In this work, we attempted to deposit chromium coating on AZ31 magnesium alloy by a novel hybrid ion beam deposition system, which includes a linear ion source......
in a nitrogen atmosphere with cool water. The pre-alloy was prepared by a jointly charging one-melting technique. The coating was deposited with a plasma gun. The schematic diagram of the device is shown... Trans. Nonferrous Met. Soc.

resistance of C/C composites, a double SiC protective coating was prepared by a two-step technique. Firstly, the inner SiC layer was prepared by a pack cementation technique, and then an outer uniform... and dried at 373 K for 10 h. The double SiC coating was prepared by a two-step technique of pack cementation and low pressure chemical vapor deposition (LPCVD). In the first step, using Si and C as the raw......
electrophoretic deposition (EPD) technique in aqueous media. The zeta potentials of different α-Fe2O3 suspensions with different additives were measured as a function of pH to identify the optimum... α-Fe2O3 coating from aqueous suspension is a feasible, low-cost and environmental friendly method.Key words:electrophoretic deposition; Fe2O3 coating; aqueous solutions; zeta potential......
Characterization and wear resistance of macro-arc oxidation coating on magnesium alloy AZ91 in simulated body fluids CHEN Jun (陈 君), ZENG Rong-chang (曾荣昌), HUANG Wei-jiu (黄伟九), ZHENG Zi-qing (郑自... characteristics of the macro-arc oxidation (MAO) coating on Mg alloy AZ91 were examined by means of nano scratch tester. The corrosion and erosion corrosion behavior of AZ91 with and without MAO coating were......
/Ti/SiO2/Si substrates by a multilayer spin-coating technique at 4 000 r/min for 30 s. Graded BST thin films were formed by sequentially depositing two layers of each composition onto the substrates...
